Abstract

INDONESIA:

Foramen mentale merupakan suatu saluran keluar pembuluh darah dan syaraf yang terletak pada korpus mandibula. Pengukuran garis tegak lurus pada foramen mentale dan kortikal mandibula mempengaruhi pengukuran dua indeks yang digunakan untuk mendeteksi dini osteoporosis. Penelitian ini mensegmentasi foramen mentale pada citra Dental Penoramic Radiograph (DPR) dengan mengambil Region of Interest (RoI) dari foramen mentale tanpa tampak gigi dan kortikal. Metode yang digunakan yaitu thresholding fuzzy type II dengan mengasumsikan histogram citra sebagai himpunan fuzzy sehingga didapatkan suatu output berupa nilai ambang threshold (T). Peneliti menggunakan tambahan metode segmentasi yaitu metode transformasi watershed serta menganalisis region yang paling berarti sebagai objek foramen mentale. Sampel percobaan menggunakan 20 citra DPR kelompok osteoporosis, sehingga ada 40 citra RoI foramen mentale yang diuji. Hasil percobaan menunjukkan 13 citra berhasil mendeteksi foramen mentale. Aplikasi mampu mendeteksi foramen mentale dengan prosentase keberhasilan sebesar 32.5%, sedangkan kinerja metode thresholding fuzzy type II untuk menunjang aplikasi ini memiliki akurasi, presisi dan recall sebesar 93.39%, 70.53% dan 0.57%.

ENGLISH:

Foramen mentale is blood vessel and nerve canal located in mandibula corpus. The measurement of perpendicular line of foramen mentale and mandibula cortical is measurement of two indexes which used for immediate detection of osteoporosis. The research segments foramen mentale from Dental Panoramic Radiograph (DPR) image by extracting Region of Interest (RoI) from foramen mentale excluding tooth and cortical. Proposed method is type II fuzzy thresholding by assuming image histogram as fuzzy set which generate threshold value (T) as output. The research uses watershed transformation as additional segmentation method and analyzes the best region as foramen mentale object. Sample experiment using 20 DPR image group of osteoporosis, so there are 40 images RoI foramen mentale tested. The experiment result indicate 13 images successfully detected the foramen mentale. Result indicates that the aplication performance to segment foramen mentale as object is 32.5%, and the performance of type II fuzzy thresholding method has accuration, precision and recall for 93.39%, 70.53% and 0,57%
